The present utility model provides a match mold for a hollow metal bar continuous casting device, including a base and an extension body, which extends perpendicularly with respect to the base, wherein: the base includes an aperture adapted to allow passage of liquid metal into the casting device; and the extension body includes a radial projection adapted to exchange heat with a cooling system of the continuous casting device.

The present invention provides a system for the production of an iron component by continuous casting including a mold adapted to receive liquid metal through an inlet channel defined in the match mold, which is disposed at least partially within the mold.
